APPARATUS FOR DYEING YARN.

SPECIFICATION forming part of Letters Patent No. 395,195, dated December 25, 1,888.

Application filed December 16, 1887. Serial No. 258,070. (No model.)

To all whom it may con/cern:

Be it known that I, URBAN WELDoN, a resident of the city of Cohoes, in 'the county of Albany and State of New York, have invented certain new and useful lmprovem ents in Apparatus for Dyeing Yarn; and l do hereby declare that the following isa full, clear, and exact description of the invention, that will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specilieation.

Similar letters refer to similar parts Vin the several figures therein.

y invention relates to improvements in apparatus for dyeing yarn 5 and it consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims, the main features being a vat for containing the dye-stuff and a dipping-wheel rotary therein for supporting skeins of yarn and dipping the same in the dye-stuff at each revolution of the wheel.

The objects ofthe invention are set forth in the following description.

Figures l and 2 ot' the4 drawings are respectively side elevation and cross-sectional views of a pair of sticks employed in supporting skeins of yarn. Figs. 3 and --l are similar views showing a modified form of sticks. Fig.` 5 is an end elevation of a dipping-wheel and vat, wit-h a portion of the head forming one end of the wheel broken away to show7 the inner face of the opposite head. Fig. 6 is a central longitudinal section of the hub and one of the wheel-heads. Fig. 7 is a side elevation of two ot' the yarn-supporting sticks secured together by end st.r Figs. S and 9 are longitudinal sections ot' one side of the dippingwheel, showing modified forms of construction and arrangement of the yarn-supporting sticks.

In my apparatus a rotary dipping-wheel is provided with a series of flanged longitudinal sticks or rods, on which the skeins of yarn are separately supported, the said sticks being removably connected with the heads of the dipping-wheel, which are provided with adjusting and securing devices. The sticks for holding yarn may be lathe-turned to form annular flanges A', as shown in Figs, l and 2, or they may be p lain sticks, A2, inserted in perforatcd disks to form flanges A3. (See Fig.

I have represented three skeins of yarn, A4, as hanging from the sticks A A. lt will be seen that the (langes A' serve to keep the skeins of yarn from impinging on each other to snarl and become entangled.

The dipping-wheel is composed of a hub, B, having at each end a circular head, B and B2, and gudgcons B3, projecting one from each end and rot-ary in boxes on the upper edge of the ends B'L of the vat B5. One ol' the gudgeons lis provided with a pulley, B6, fixed thereon, to which power may be applied to revolve the wheel. The inn er faces of the wheelheads are provided with slots C near their periphery, adapted to receive the ends of one of the pair of yarn-supporting sticks. The heads are also provided with a boss, D, near the hub, having slots D', adapted to receive the ends of the other one of the pair of yarnsupporting sticks. One of the pair of sticks is inserted in one of the slots near the periphery of the wheel-heads and the other in one of the slots near the hub of the wheel-heads, as shown in the respective iigures. The sticks are held in the inner or hub slots by the buttons a, pivoted at a to the head. rllhe buttons are held in place by a spring, a2. The middle button in Fig. 5 is shown pushed to one side bythe end of the stick. of its slot in the position it occupies just as it is being inserted in its slot.) After the stick enters the slot the spring a2 forces the button to a position in a radial line with the stick, to hold it within its slot, as shown.

The position of the sticks in the peripheral slots may be adjusted radially of the wheelhead by means of the blocks as, adapted to slide in and longitudinally of the slots. These blocks are provided with longitudinal slot-s d4, adapted to receive a bolt, a5, which passes through the slot and through an aperture in the wheel-head, having on the opposite side of the head a thumb-nut, at", by which the slotted block can be drawn tightly against the wheel-head, tohold it in any desired position in its retaining-slot. By loosening the thumb-nut the block can be slid longitudinally of its retaining-slot to the desired position to give the required degree of tension (Shown just outside ICO to the skeins of yarn supported bythe sticksV A, and then secured in said position by screwing up the thumb-screws.

The position of the skeins of yarn is shown by the dotted lines, and it will be observed that the skeins occupy planes radial to th dipping-wheel.

It' the yarn-supporting sticks are so adjusted that the skeins are not taut between the sticks, each end of the skein will 'fall below and away from the lower one of its pair of supportingsticks once during each revolu tion of the dipping-wheel-fi. e., when the skein hangs vertically above and below thc hub of the wheel. Such falling away from the stick permits the dye-stuff to permeate all parts of the skein equally, which it might not do if the yarn were held taut against its supportingsticks during the entire operation.

The sticks may be fixed at the proper distance apart by end stays, F, secured to the ends of the sticks, as shown in Fig. 7. Then the sticks are so stayed, the inner faces of the wheel-heads may be provided with radial slots extending` from the periphery of the heads to points near the hub, as shown by dotted lines E in Fig. 5. The sticks so stayed are shown in Fig. 9 secured in slots by buttons F.

That I claim as new, and desire to secure by Letters Patent, is-

l. In an apparatus for dyeing yarn, the combination, with the heads of a rotary dipping-wheel, of a series of loi'igitudinal sticks which are provided with annular flanges for separately holding skeins of yarn, substantially as and for the purpose described.

2. In an apparatus for dyeing yarn, a rotary dipping-wheel having heads which are provided with radial slots C at their peripheries, adjustable bearing-blocks placed in said slots, recessed hubs D,buttons a, and springs a2, and a series of longitudinal sticks, A, provided with flanges A', the parts being constr ucted and combined substantially as shown, for the purposes set forth.

In testimony whereof I have hereunto set my hand this 14th day of December, 1887.
